After and alongside concert tours in the early 1980s with musicians and bands such as Udo Jürgens, Eloy, Drahdiwaberl, Hansi Lang and Milva, Leverenz increasingly turned to her own projects.
[1] With the pianist Olaf Joksch she gave cabaret evenings in Frankfurt and Offenbach in the 1980s (among others (K)ein Liederabend - Liederbissen von Bach bis Zappa at the Theater am Turm [de] 1985-1986 and 500 Jahre Filmmusik at the Alte Oper 1986–1988).
[2] As her own projects, she realised among others Staffellauf im Wespennest (1987), a performance with singing and pantomime with Olaf Joksch, the operetta talk show Lieber reich aber glücklich (1995) with the actor Peter Bauer and the pianist Elisabeth Süsser and the multimedia Concerti Piccoli for the 100th birthday of Marie Luise Kaschnitz.
For the composer René Staar, she wrote the libretti for Fortunes Of War (1997, about Al Capone) and The Gypsy Boy (1998, about Federico García Lorca).
Private singing lessons with her took among others Xavier Naidoo, Sabrina Setlur, Sebastian Hämer, Christine Kaufmann, Bela B., Nadja Benaissa, Kevin Russell, Stefan Weidner, Lisa Da Costa and Beukes Willemsen.
